Review: Night and Day Difference: YoLink Smart Water Valve Controller System is a Game Changer! - After having constant issues with the Guardian water leak detection system, I was on the hunt for a more reliable and user-friendly alternative, and I’m so glad I found the YoLink Smart Water Valve Controller! The installation was a breeze, taking me around 30 minutes to set up the controller, and a bit more time to configure and place 16 leak detectors around the house. The process was straightforward and easy, even without the need for a plumber – it's truly DIY-friendly. Now, comparing this to the Guardian system is like night and day. The Guardian was a headache, constantly failing, poorly designed, and honestly, it cost a fortune. Each Guardian controller was $50, and they kept failing on me. With YoLink, I’ve found a much more reliable and cost-effective solution that works exactly as advertised. Setting up the YoLink system was incredibly intuitive. The app is user-friendly, and I was able to easily configure the settings, including the wireless range, which works flawlessly. Even with multiple walls between devices, the system remained reliable with no drop in connection. It’s great to have peace of mind knowing that everything is connected, and I can manage it all from my phone. One tricky part for me was figuring out how to automatically trigger the water valve to close when a leak is detected, but I solved that by using the Automation tab in the app. Once I set up the events, the system worked perfectly. Thankfully, I didn’t need to watch the instructional videos since I’m already familiar with these kinds of systems. I’m beyond impressed with how well this system works. It’s easy to update and configure, and I now have total peace of mind knowing my home is protected against water leaks. If you’re tired of dealing with a poorly designed, expensive system like I was, I highly recommend the YoLink Smart Water Valve Controller! It’s been a total game changer for me. **A++++ – Highly Recommended!**
Review: Already saved me from one flood! - TLDR: These are *AWESOME*!!!!!!!! I have to admit, I was *really* skeptical of the "YoLink" family of products when I bought them. It sounds kind of hoaky and well, I didn't think it would work all that well. BOY, I WAS WRONG! I bought a YoLink Hub with leak sensors and bought this 3-pack to protect extra areas of my home. About a week after installation, they went off when my water heater relief valve let go and the water got shut off immediately so that the flood was very limited in scope. These devices are awesome so far, and I am so glad I have bought them. I also bought sensors for my refrigerators and a water shutoff valve motor that automatically shuts the water off to my house if a leak is detected. I can see the status of my home from anywhere that I have cell signal! Installation: Couldn't be easier. Get the app from the app store, click on the "scan" button and scan a QR code on the back of the device. It gets added to your YoLink Home, and after you power it on, you get instant feedback as to the health of the device, the health of the connection, and the status (alarmed or normal). 10 seconds per device to install. You can name each one, organize them into rooms, and many other options. Function: I tested the leak sensors by licking my fingers and bridging the contacts with my wet finger. Each one I have bought has alarmed on all of the sensors on the device. There are two sensors on the bottom and one on the top (cleverly in a little "cup") that would hold water if it were spraying everywhere. App: The app is pretty decent. I get a dashboard that lets me see my whole home at a glance. There are a few confusing parts, like Scenes, and "Automation" which are not immediately obvious. But they have a few videos that help and their customer service was pretty responsive. Range: I have a sensor in the basement freezer and one in my kitchen refrigerator. While they aren't horribly far from the hub, they have full strength signals despite being in cold temperatures and inside the refrigerator boxes. Battery Life: I cannot comment yet, but they are not replaceable and are supposed to last 5 years. I hope that's true. But even if they last a couple years, the disaster they save you might be worth it. Installed locations: Under each bathroom sink, Under kitchen sink, Under each toilet tank, near my washer and dryer, behind my refrigerator (icemaker has leaked before), Near my boiler, near my water heater, near the A/C condensate pump. Overall, I couldn't be happier with my YoLink system. This was well worth the money, especially since it already saved me from one bad flood.

## Features

- NO WiFi WORRIES! YoLink devices communicate by LoRa, an industrial-grade protocol that provides up to ¼ mile open air range. Devices do NOT connect to your network or even to the internet; they communicate with the Hub (Not included!). Long range, obstruction penetration, no reliance on WiFi, and fully-encrypted communications provide more than most ask for from their smart home system!
- SET IT & FORGET IT! Installs in seconds! The YoLink wireless Water Sensor could not be easier to install; just place near or under the equipment you wish to monitor. Suggested uses are near or under, toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, in or near sump pumps, and by any other location subject to water leaks and flooding.
- EXTREME LONG RANGE! Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property.
- NO WIFI, NO INTERNET, NO POWER? NO PROBLEM! Our patented Control-D2D device-to-device pairing, over our LoRa-based wireless network, allows for devices to be paired to each other, in such a way they will continue to operate, even if WiFi is flaky, the internet goes down, or the AC power goes out!
- START SMART! A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
- BATTERIES INCLUDED! Two replaceable AAA batteries, good for over 5 years, are included!
- AVAILABLE AS A STARTER KIT! Search for B0BFR7WJQT

## Questions & Answers

**Q: Can you replace the batteries?**
A: Yes, there are rubber tips on the 4 corners of the bottom, you can remove them and unscrew 4 screws and open the sensor, to replace two AAA batteries. The battery can run more than 5 years. You can search on YouTube video of how to change the YoLink water sensor's battery and can find the videos. Thanks!

**Q: Is this a dumb proprietary system or does it ingrate with smart home technologies, ie Z-wave Zigbee etc?**
A: It is not Zigbee, WiFi or Z-Wave wireless technologies, all these wireless technologies only work for short range. The YoLink system use the longest wireless range and lower power consumption. It works with the YoLink hub and can be integrate to other system through the Alexa routines, IFTTT or YoLink's API. Thanks!

**Q: Do you have any water leak sensors that have audio as well as the app reminder? Or are these just app reminders?**
A: These 3 pack leak sensors don't have build in audio sound. We have YoLink water leak sensor 2 which has build in sound, both them have app push notifications, emails and text message for leak alert.

**Q: What frimware version do you have on these D or E? Tx**
A: Mine came with 030E installed. The sensors I bought previously had 030D installed and still aren't being offered the 030E update even though they are the exact same model number. I also don't know the difference between 030D and 030E as they don't seem to publish any firmware changelog that I can find.

### ⭐⭐⭐⭐⭐ Great Product
*by G***E on January 6, 2026*

I bought these after we had a leak on the line going to the ice maker on our refrigerator. We had quite a bit of damage, and I told myself "Never again". They are easy to set up and send an alert to my phone when they sense a leak. I highly recommend them.
